I thought Pokemon and Earthbound were pretty good. Pokemon for actually having interesting combat and game mechanics, Earthbound for not taking itself seriously, not having random battles, having monsters run from you when you were much stronger than them, and having it be an automatic win against them in those cases as well. Also, you could name your ultimate attack, so if you want to "cock thrust" the other guy into oblivion, go ahead.
Chrono Trigger has some interesting mechanics, like a trial part where seemingly insignificant things you did at the start of the game come into play. FFV had an interesting job system. Both of those games ended up sucking too much for me to finish them.
I don't know, I think if you took out the tedious combat and the fact that the storylines usually go to shit halfway through (ok, I've only played like 6 JRPG's), they probably have about the same appeal as adventure "games". IE, you're not really doing anything (pixel hunting in adventure games), but you feel like you are.

Are there many japanese dungeon crawlers who utilises character skill in anything but combat, though? Trap & lock disarming, sneaking, diplomacy, etc?
Unlimites Saga has some (these are just a few):
Weaponsmith:
Effect: [Shop]: Increases the type of weapons you can make at Mythe's
workshop.
Diplomacy:
Effect: [Field]: Hit a O panel on the monster reel to make the
monster go away. When you hit a X panel nothing happens. When you hit a bomb
panel the monster will attack.
Monger:
Effect: [Shop]: Allows you to buy items at a reduced price.
Sharpeye:
Effect: [Field]: Lets you know whether there is a trap on a chest
and what type of trap it is. Also prevents the reel of the trap/lock on the
chest from being difficult.
Locksmith:
Effect: [Field]: Lets you unlock treasure chests and doors that are
locked.
Cave Guide:
Effect: [Field]: Shows you a complete view of a cave map.
Also makes it easier to find treasure.
Panel level difference: The higher the panel level, the wider the scope of the
area that you can see of the map.
Eavesdrop:
Effect: [Field]: Shows where beasts, wildlings, birds, insects and
undead are on the map.
